PNEUMATICI SEPARATOR FOR. SPINNING FRAMES.

application mea nay 2a, 1925,*seria1 No. 33,494, and in Belgium apra 1s, 1925.

The present invention relates to improvements in and relating to installations comprising a relatively great number of winders or throstle-irames provided with pneumatic suitable conduits.

It follows that all the winders which work generally on threads of different quality, are all supplied with air at the same pressure and the same degree of moisture and that' the air of the hall supplied by means of a single blower to the dierent apparatus, re-

turns afterwards to it and produces a re,

turn-current towards the blower.

That great draught of returning air prevents the maintaining of a more intense moisture in certain parts of the room according to the quality of the treated wool at these spots.

The present invention has for its object to obviate these inconveniences by suppressing more particularlyv the fores'aid great draught of returning-air. To this end, each Winder or each throstleframe is providedwith an independent apparatus for producing the moistened compressed air. v In the case of a Winder, the inventio'n provides in the midst of each ily, on the left and on the right of the head stock, an electric motor acting on a blower or an air-pump directly connected to the conduit distributing the air currents between the threads.

In order to vary the degree of moisture according to the nature of the thread treated by the Winder, the moisting apparatus acts on the air drawn in by each air-pump or blower, to humect it at agiven amount.

Other details and characteristics will appear by the description of the drawings showing by way of example a form of embodiment of the invent-ion.

Fig. 1 is a schematical side view of an apparatus with four winders.

said Windel-s for producing the moistened compressed air necessary for supplying the anti-marrying element.

Said means comprise an electric motor 2 driving a blower 3 discharging in a conduit 4 directly connected to the tube 5 disposed along the Winder, and which delivers jets of air assuring the isolation of the winderthreads as known.

The pressure of the air supplied by the blower depends on the motor speed which can be varied by means of the controller 6 of the motor.-

The moisture of the air is realized by means of moistening elements of any known type, which supply pulverized water, moistened air or air saturated with water in the inlet of the blower. In Fi 1, the moistening elements are' shown sc ematically by 7.

'It is obvious that the blower may be replaced by an air-pump or the like.

As indicated by the arrows, airv supplied by the blower of a Winder* circulates according to a closed circuit and thus it is possible to control the pressure and the moisture of the air acting on the threads of a winder independently of the adjacent Winder. It

is to be noted that winders are apparatus A the threads'passing between the cylinders 9` and 10, the cylinders 10- being applied a ainst the rooves of the cylinder 9 by suita le means not shown). v

What we claim is:

1. In a plant comprising a lurality of continuous spinning frames wools arranged in one chamber, a neumaticseparating device preventing dou threads; and means for circulating' pure moist air in a closed independent circuit and lacting on the threads of each continuous spinning frame.

s 2. In a plant comprising a lurality of continuous spinning frames Forl combed wools arranged inone chamber, a pneumatic separating evice preventing doubling of the threads; and on each continuous spinning frame a pump forcing moist air between the threads and sucking in pure moist air fed to the 4vicinity of ther spinning frame.

/3'1n a plant comprising a lurality of continuous spinning es r combed or combed g of the l wools arranged in one chamber, a pneumatic separating device preventing doubling of the threads; and on each continuous spinning frame a pump, a humidifier fitting into the intake opening of the pump, a pipe connected with the latter to feed pure moist air between the threads; an electric motor actuating the pump whose intake sucks in pure moist air in the vicinity of the spmmng frame. Y 1 In testimony whereof we have signed our names to this specilication. Y
